STEP 1: Copy & share the following without the quote marks on Twitter (if you aren't on Twitter, use Facebook, or do BOTH!): "Want a FREE copy of King's Cross by Tim Keller? RT this & comment at Reformissionary to enter! http://bit.ly/g9eGgh "

STEP 2: Leave a comment below (so I can verify you did step 1). Include your full name and real email address (kept private) so I can contact the winners. For fun, guess the number of books (from my library) sitting on my desk right now. It's between 1-100.

I will randomly choose 2 winners in the late afternoon/early evening on Friday (18th).
